The number of individual species of insects so far known is over a million and each of these species numbers into millions even billions of individuals. Doubtless, insects are harmful to us in one way or another but the benefits they offer in so many visible and invisible ways are also great that they cannot be assessed in terms of money. One radical quote on insects reads “If all mankind were to disappear, the world would regenerate back to rich state of equilibrium that existed ten thousand years ago; if insects were to vanish, the environment would collapse into chaos” – Edward O. Wilson. Man’s future on this earth may very well depend on how well we understand the insect world – how well we fight our insect enemies and protect ourselves against them- how well we protect our insect friends. A study of the insects which are variously related to the welfare of mankind is referred to as economic entomology. Such studies are usually made with reference to the habits and habitats of the insect species. Insects are generally classified into three convenient groups from the point of view of the economic nature, namely harmless, harmful and beneficial insects. This classification, however, is not a rigid one and is often subject to alterations depending on conditions. Certain insects which are considered not harmful may under some other favourable conditions become serious pests and vice versa. The scope of the present course is not the study on how many ways insects are beneficial to us but on how many ways they are harmful to us particularly as pests of crops and stored grain. In this section, different ways in which insect pests are harmful to us are classified. 1. Destroying crops and valuable plants: Insects destroy all kinds of growing crops and other valuable plants by feeding on leaves, stem, bark, roots, buds, flowers and fruits. They also bore or tunnel into shoots, stems, roots and fruits feeding on internal contents. Insects are known to cause cancerous growth/ galls within which they live and feed. They cut and carry parts of plants for construction of nests or shelters. Many species of insects are reported as vectors disseminating microorganisms of plant diseases, namely, viruses, bacteria, fungi etc. 2. Annoying and injuring man and animals: There are several ways in which insects annoy and injure man and animals, both domesticated and wild. Droning, humming and buzzing they produce is annoying to everyone. The foul odour they emit, offensive taste of their secretions/excretions they leave on fruits, food and dishes cause suffering. Pinching and causing painful disfiguring blisters on any part of the body, they may come in contact with. Accidental entry into the eyes, ears, nostrils or alimentary canal causes myiasis, a painful muscle damage. 3. Injecting venoms:
